Design and description

The L'Adroit class was a slightly enlarged and improved version of the preceding Bourrasque class. The ships had an overall length of 107.2 meters (351 ft 8 in), a beam of 9.9 meters (32 ft 6 in), and a draft of 3.5 meters (11 ft 6 in). The ships displaced 1,380 metric tons (1,360 long tons) at standard load and 2,000 metric tons (2,000 long tons) at deep load. They were powered by two geared steam turbines, each driving one propeller shaft, using steam provided by three du Temple boilers. The turbines were designed to produce 31,000 metric horsepower (22,800 kW; 30,576 shp), which would propel the ships at 33 knots (61 km/h; 38 mph). The ships carried 386 metric tons (380 long tons) of fuel oil which gave them a range of 3,000 nautical miles (5,600 km; 3,500 mi) at 15 knots (28 km/h; 17 mph).[1]

The main armament of the L'Adroit-class ships consisted of four Canon de 130 mm Modèle 1924 guns in single mounts, one superfiring pair each fore and aft of the superstructure. Their anti-aircraft armament consisted of a pair of Canon de 37 mm Modèle 1925 guns. The ships carried two above-water triple sets of 550-millimeter (21.7 in) torpedo tubes. A pair of depth charge chutes were built into their stern; these housed a total of sixteen 200-kilogram (440 lb) depth charges. In addition two depth charge throwers were fitted for which six 100-kilogram (220 lb) depth charges were carried.[2]

Construction and career

Boulonnais was laid down on 4 May 1926, launched on 1 June 1927 and completed on 25 June 1929. She was sunk on 8 November 1942 off Casablanca, French Morocco, during the Naval Battle of Casablanca by the United States Navy heavy cruiser Augusta or light cruiser Brooklyn.

gollark: it totally is.
gollark: Eh.
gollark: But my worry with higher-end monitors and panels is that it'll briefly be very shiny and cool, but then I'll get used to it, find the old monitors bad, and be forced to spend a lot more for not much actual benefit later.
gollark: Apple really love vendor lock in.
gollark: I'm probably just used to really low-quality monitors.
